Shopify cross-sell app comparison

Shopify cross-sell apps compared: add-on offers that work with the rest of your discounts

By the Discount Prime team | Tested Nov 2, 2026 | Last updated November 2026

A cross-sell widget is easy to add. The hard part is what happens in the cart: the add-on discount meets a volume deal, a free gift threshold, a free shipping bar, and items with thin margin. We set up cross-sell offers on a live Shopify store next to those discounts, then checked how 13 popular upsell and recommendation apps document the same situations.

Frequently bought together add-ons on a headphones product page, 10 percent off each

Key takeaways

  • Discount Prime cross-sell recommends add-ons on the product page, in the cart, or both, with an optional add-on discount: percent off, amount off, or a fixed new price.
  • Recommendations come from manual picks, a rule-based pool (collection, tag or vendor), or Smart suggestions.
  • Smart suggestions skip offers under a margin floor and flag products with unknown cost before they go live. None of the 13 apps we reviewed documents margin-aware suggestions.
  • The merchant stays in control: every suggestion can be added, pinned or dismissed.
  • The add-on discount runs in the same engine as volume, bundle, free gift, upsell and shipping campaigns, with "Best deal wins" deciding overlaps.

How we tested

We ran the offers on a live store next to other discounts and read what 13 popular apps publish about the same situations.

Store
Shopify development store, Dawn theme, Discount Prime Ultimate, 138 test orders.
Date
November 2, 2026.
Campaign
Headphones (trigger) with carry case and ear tips as add-ons at 10% off, on the product page and in the cart. Live at the same time: a free gift over 200 dollars, a gift ladder at 500 and 1,000 dollars, free shipping over 150 dollars, and an upsell campaign.
Competitors
Competitors were not installed. Their columns reflect App Store listings, pricing pages and help centers accessed November 2, 2026. "Not documented" is not "not supported".

The 13 apps we reviewed

Rebuy's listing showed "not currently available on the Shopify App Store" on Nov 2, 2026.C16

Three ways to choose what to recommend

Pick each add-on yourself, match it from a rule, or review a ranked list of suggestions.

Manual picks

Choose up to 6 products for a trigger.

Pool

Match products from a collection, tag or vendor, exclude what should never appear, and show the top N ranked by units sold in the last 180 days. New products that join the collection enter the pool automatically.

Smart suggestions (Beta)

A ranked list for the trigger product that you review before anything goes live.

Trigger by product with minimum quantity and spend, and three offer sources: manual picks, pool, smart suggestions
Pool offer with a match type, exclusions and items to show, ranked by units sold in the last 180 days

Smart suggestions you can audit, not a black box

Automatic recommendation engines often decide for you. Discount Prime Smart suggestions show the list first and let you decide.

What competitors document (as of Nov 2, 2026)

None of the 13 apps documents showing co-purchase evidence or using product cost when choosing suggestions. Selleasy shows an AI "pitch" plus views, clicks and conversions per recommendation and filters out-of-stock items. Rebuy states its price filter "is not a margin control". Candy Rack lets merchants choose Gemini, its own engine or Shopify's recommendations per placement. No app documents an approval step before its automatic suggestions go live.C9 C21 C28 C29

The four field tests

Each one is a merchant situation: how Discount Prime handles it, and what other apps document for the same case.

Test 1. Add-on discount next to a free gift and free shipping

Setup

Headphones at 219 dollars in the cart, carry case added from the widget at 10% off.

What happened in Discount Prime

Carry case 25.00 to 22.50, labeled "Frequently bought together (2.50)". The free notebook was added automatically at 0.00 and free shipping over 150 dollars applied. Checkout showed all three lines, total savings 14.50.

What competitors document (as of Nov 2, 2026)

Outside Shopify Plus, apps follow Shopify's "one product discount per line, highest wins" rule. Rebuy's same-line stacking is Plus-only and it states third-party discount apps are not integrated.C8 C19 C20

Added state after the shopper adds the carry case
Cart with the add-on discounted and labeled Frequently bought together, and a free gift added automatically
Shopify checkout showing the add-on discount, a free gift and free shipping together

Test 2. When an add-on already has a discount

The setting in Discount Prime

"Best deal wins" (default) gives the shopper whichever discount is worth more, the add-on discount or the product's own discount, never both. "Stack on product discounts" adds it on top.

What competitors document (as of Nov 2, 2026)

No app documents a best-deal-wins choice for add-ons.C8 C19

Add-on reward with max discounted units, apply-when rule, and Best deal wins or stack on product discounts

Test 3. Control over how many units are discounted and when

The setting in Discount Prime

"Max discounted units" per recommended product and "Apply when": "Trigger and add-on both in cart" or "Only if added from the widget". Fixed new price is supported.

What competitors document (as of Nov 2, 2026)

Candy Rack discounts one upsell unit by default, and more units need manual Shopify discount edits that reset when the offer is edited. LimeSpot allows one bundle per cart and discounts only the whole bundle.C27 C36

Apply when options: trigger and add-on both in cart, or only if added from the cross-sell widget
Reward types: no discount, percent off, amount off, or a fixed new price per add-on

Test 4. Two campaigns want the same trigger product

Setup

A second cross-sell campaign using a trigger product that a live campaign already holds.

What happened in Discount Prime

The admin shows which campaign already holds the product and offers "Give this campaign priority" or "Take this one". Saving never fails silently: the campaign is stored as a Draft with the reason.

Product overlap check: one cross-sell campaign per trigger product, with a priority control

Inside the campaign

Every cross-sell offer is one campaign. Here is what the merchant sees.

Cross-sell scenarios: frequently bought together, complete it with an add-on, pairs well with, reorder essentials
Ready-made cross-sell scenarios.

Where other apps are stronger

Other apps lead on placements, review volume, A/B testing and the range of data behind their suggestions.

  • More placements. Popups on add to cart, checkout extensions and post-purchase pages (Selleasy, Candy Rack, Wiser, ReConvert, AfterSell, Rebuy, LimeSpot). Discount Prime focuses on the product page and cart, with no popups.C8 C29 C15 C23 C24 C17 C35
  • Review volume. ReConvert (about 3,100), Selleasy (about 2,700), Essential (about 2,500).C23 C5 C39
  • A/B testing. Built in for Wiser, ReConvert, AfterSell and paid tiers of Rebuy, Glood and LimeSpot.C12 C23 C24 C17 C34 C35
  • Broader behavior data. Rebuy and Wiser use broader behavior data (views, ratings, segments). Our Smart suggestions are in Beta.C21 C14

Shopify cross-sell app comparison FAQ

Where does Discount Prime show cross-sell offers?

On the product page, in the cart, or both. You can also run an offer without showing it, for tracking only.

Can the add-on have its own discount?

Yes: percent off, amount off, or a fixed new price, with a cap on discounted units and a rule for when it applies.

What happens if the add-on already has another discount?

With Best deal wins the shopper gets whichever discount saves more, never both. You can switch to stack on product discounts.

How are Smart suggestions chosen?

They are ranked for the trigger product, skip offers under a margin floor, and flag items with unknown cost. You add, pin or dismiss each one before it goes live.

Do I need order history for Smart suggestions?

No. New stores get a starter set from the catalog that improves as orders come in.

Can recommendations update automatically when I add products?

Yes, with a pool based on a collection, tag or vendor. New matching products join the pool.

Which plan includes cross-sell?

Cross-sell starts on Prime. Smart suggestions need Ultimate.
